Abstract

ANTENA COMPLEJA CON RADIADORES DE RANURA DESPLAZADOS POR INCLINACION PARA ELIMINAR LOBULOS DE RANURA. LA ANTENA (20) ESTA FORMADA POR UNA AGRUPACION BIDIMENSIONAL DE ABERTURAS RADIANTES DISPUESTAS EN FILAS (22) Y COLUMNAS (24), ESTANDO FORMADA CADA UNA DE LAS ABERTURAS RADIANTES COMO RANURAS (40) DENTRO DE UNA PARED ANCHA SUPERIOR (28) DE UNA GUIA DE ONDAS (26). LA ANCHURA DE LA PARED ANCHA ES MUCHAS VECES MAYOR QUE LA ALTURA DE UNA PARED LATERAL (32, 34) DE LA GUIA DE ONDAS, TENIENDO LA GUIA DE ONDAS UNA SECCION TRANSVERSAL RECTANGULAR. UN EMISOR O LANZADOR (56) DE ONDAS, CONECTADO A UNA PRIMERA PARED EXTREMA (36) DE LA GUIA DE ONDAS, EMITE UN MODO DE ORDEN SUPERIOR DE ONDA ELECTROMAGNETICA EN LA QUE EL ORDEN DEL MODO ES IGUAL AL NUMERO DE COLUMNAS DE LOS ELEMENTOS RADIANTES. LA PARED ANCHA SUPERIOR TIENE UN ESPESOR AUMENTADO DE UN OCTAVO, APROXIMADAMENTE, DE LONGITUD DE ONDA EN EL ESPACIO LIBRE.
